40 stumbles when braking.
 

So my 40 is running rough when slowing and braking. Clutch is fully disengaged and the engine runs rough and slow until I am fully stopped, then smooths out and speeds up to normal idle. Occasionally it will die but restart fine.

Thoughts?

Check float level

Also check and make sure that the engine has a good ground with the chassis - as I've seen cases where the movement of the engine changed the ground surfaces and caused an ignition issue. If it is not the float level, you might consider a large ground wire from the frame (ground cable location) to a transmission or head bolt.
